JOURNAL-BOX- SPEGIFICATION forming part of Letters Patent No. 761,246, dated May '31, 1904.. Application filed January 2, 1904. Serial No. 187,481 (No model.)

To all whom, it may concern:

A further object is to provide improved means for supporting the brass in the box both when the journal is in the box and when it is removed therefrom.

In the accompanying drawings, Figure 1 is .an end view of a car journal-box with the lid removed. Fig. 2 is a top view thereof. Fig. 3 is a vertical section on the line 3 3 of Fig. 2, and Fig. 4 is a perspective view of the cylinder containing the pressure-actuated piston which controls the lock.

Referring'specifically to the drawings, 6 indicates a car journal-box of ordinary construction; 7 the car axle or journal therein; 8, the bearing-brass, and 9 the key which holds the latter in place. In-the side wall of the box opposite the edge of the brass a hollow casing 10 is cast. This casing opens into the inside of the box through the side wall thereof and has through the top a small hole 11 for the air-pipe nipple, but is otherwise closed throughout, so that the lock cannot be tampered with either with or without tools. Within said casing is inserted a cylinder 12, closed at the inner end, except a small vent at 13, and closed at the outer end by removable cap 14:. This cylinder contains a piston 15, behind which is a coiled spring 16. The piston has a stem or bolt 17, which extends through a hole in the cap 14 and projects within the journal-box, Where'it enters a hole 8*, produced in the side edge of the brass. Opening into the cylinder on the side of the piston opposite the spring is a nipple 18, which projects through the hole 11 heretofore referred to. This nipple is adapted to receive a coupling of a pipe from the airbrake system or from any convenient airpump to release the look.

In use the pressure of the spring 16 forces the piston toward the end of the casing nearest the journal-box, with the ,bolt or stem 17 in the hole in the edge of the brass, whereby the brass is locked against removal. To release the lock, air or other fluid pressure is forced in through the nipple until the pressure of the spring-is exceeded, when the piston will move back and withdraw the stem from the hole in the brass, which can then be removed in the usual manner.

In case the axle has to be taken out of the box for any reason the stem in the hole in the brass acts to support the latter and to hold it in position. Also it holds the brass in place while the car is in motion and prevents any accidental displacement of the brass.

The embodiment illustrated shows only one cylinder; but it is within the scope of our invention to duplicate the same on the other side of the box, thereby affording double security against theft and also holding the brass in place better.

What we claim as new, and desire to seizure by Letters Patent, is-

1. The combination with a journal-box, and brass therein, of a locking-bolt engaging the brass and inaccessible without removing the brass, and means to operate said bolt and to lock the same against unauthorized operation thereof.

2. The combination with a journal-box and brass, of a concealed and exteriorly-inaccessible locking device carried by the box andengaging and supporting the brass and constructed to prevent unauthorized unlocking.

3. The combination with a journal-box, and a brass therein, of a locking-bolt engaging the brass, and fluid-operated means to unlock and operate said bolt.

4. The combination with a journal-box and brass, of a spring-pressed bolt supported on the box and engaging the brass, and means to disengage the bolt from the brass.

5. The combination with a journal-box and brass, of a spring-pressed bolt supported on the box and engaging the brass, and means operated by fluid-pressure to disengage the bolt.

6. The combination With a journal-box, and a brass therein having a hole in the edge, of a locking-bolt concealed and inclosed in a casing and Working through the Wall of the box and into said hole, and means to unlock and operate said bolt.

7. The combination With a journal -box having a brass therein, of a cylinder on the boX, a piston slidable in said cylinder, a bolt projecting from the piston into engagement With the brass, a spring in the cylinder on one side of the piston, and a fluid-pressure inlet to the cylinder on the other side of the piston.

8. The combination of a journal-box having a casing thereon opening into the box, a cylinder in the casing, a spring-pressed piston in the cylinder, having a stem projectinginto the box, a brass in the box having ahole into Which the stem fits, and a fluid-pressure inlet through the casing and into the cylinder on the side of the piston opposite to the spring.

In testimony whereof We have signed our names to this specification in the presence of two subscribing Witnesses.
